Specification of Letters Patent. l

Patented Dec. 22,- 1914.

Application filed August 4, 1910. Serial No. 575,557.

To all whom t may concern Be it known that I, PAUL RoMnuG, a subject of the King of Saxony, residing at Leipzig, in Germany, have invented a certain new and useful Improvement in Barrel- Brushing Apparatus, of which the following is a specification.

rllhis invention relates to barrel-brushing apparatus of the type in which the barrels are automatically carried to and from supports consisting of revolving rollers, arranged in proximity to brushes which are pressed against the barrel revolving on said rollers.

rI`he invention consists in an improved arrangement and means for moving the 'brushes to and from operative position, and

is primarily intended for use in machines in which the barrels are conveyed to and from the supporting rollers by an automatic conveyer such as shown in the specification filed with my co-pending application Serial No. 575555. In connection with machines of this kind my invention has the special advantage that the brushes all swing aside, after operation, to make a free path for the conveyer.

The invention is illustrated in the annexed drawing, which is a front elevation of the brushing apparatus.

rIhe barrel supporting rollers 16 are driven by a shaft 5 and suitable connecting ofear.

o The brushes for cleansing the heads and wall of the barrel are hinged to bell cranks 26 and 27 pivoted at 28 and 29 respectively to spaced standards 25, so that both sets of brushes can be swung outward into the positions indicated by dotted lines in the drawing, enabling the barrel to be deposited on the supporting rollers 16, and also to be removed after the brushing operation. The bell cranks 26 are connected to the bell cranks 27 by link rods 30, which are pivoted to the bell cranks 26 and slotted to engage pins projecting from the bell cranks 27, so that when the brush-carrying arms of the latter have been swung outward to a certain extent their continued movement pulls the brush-carrying arms of the bell cranks 26 outward. The movable connection between the bell cranks enables both sets of brushes to continue inefficient operation though they be unequally worn. Moreover, when the brush carriers swing inward, the brushes acting on the barrel-heads come into operation before the other brushes. This is an important feature, inasmuch as if the walltreating brushes came down first the barrel would tend to jump off the supporting rollers.

The bell cranks are rocked outward by means of arms 31 fixed to the pivots 29 and connected by rods 32 to actuating llevers 33. The levers 33 may be actuated by cams fixed to a crank shaft of the conveyer shown in my prior specifica-tion cited, and operate so that when a fresh barrel has been placed on the supporting rollers 16 the levers allow brush-carriers to swing inward with an even, regular motion. i

Inasmuch as the brush-carrying arms, in rocking toward the barrel, are moving from a more or less vertical position to an inclined or horizontal position, the tendency of the weight of these arms (including the weight of the brushes) is to increase the inward thrust of the brushes as they approach the support. The eflect of this weight alone would, therefore, be to apply greater brush pressure to small barrels than to large barrels, whereas in practice the contrary eect is desirable, that is to say, the brushes on large barrels should be greater than that on small barrels. I obtain this contrary effect by means of weights 36, 37 on the other arms of the bell cranks. The disposition of these other arms is such that the effect of their weight, in imparting inward thrust to the brushes, is greatest when the brushes are remote from the support, and gradually decreases as the brushes approach the support. Consequently the brush pressure is greater, when operating on large barrels, than when operating on small barrels.

What I claim is my invention and desire to secure by Letters Patent of the United States is 1. In a barrel brushing device, the combination with a barrel support consisting ofl rollers, of brushes adapted to contact with the heads of the barrel, levers carrying said brushes, other brushes adapted to contact with the wall of the barrel, levers carrying the last mentioned brushes, and means connecting the last mentioned levers with the first mentioned levers in such manner that a limited lateral movement of the levers with relation to one another is permitted.

2. In a barrel brushing device the combination With a barrel support consisting of the pressure of rollers of brushes adapted tokcontaetrvvit'h the heads of the barrel, levers carrying said brushes, other brushes adapted to"eoiitaet with the Wall of the barrel, levers carrying the last mentioned brushes, slotted links Connecting the last mentioned to the first mentioned levers, and means for positively swinging the last mentioned levers away from the barrel support.

3. ln a barrel brushing device the conibination, with a barrel support consisting of rollers, 'of a bell lCrank lever adj aeent said support, said bell crank lever having a Gopes @E this'patent may be btained'for ve cents each, by addressing the Weighted arm, and a brush carried by the other arin of said bell crank lever, the latter being vvdisposi-1d to rock said brush toward said support, With a thrust in part due to the Weighted arm, the latter approaching the vertical as the brush approaches the barrel.

ln Witness whereof I have signed this specification in the presence of tWo Witnesses.
